How to create a macOS Sequoia bootable USB for installation on Windows 10 PC?
- Aug 15, 2025
I used UltraDMG to create a macOS bootable USB on Windows, and it worked like a charm for reinstalling macOS Sequoia on my MacBook Pro. Highly recommend it!

P.S. To save time during dmg burning and macOS installation, it is recommended using a USB 3.0 or above USB flash drive instead. macOS Sequoia is quite big and it could take hours to install on a slow USB 2.0 drive.
How to create a macOS sequoia bootable USB on a Windows computer? That's a unique challenge! I've been in your shoes before.
- You'll need a blank USB drive with at least 16GB of free space. Make sure it's not too small, or you might end up with an error message. I learned this the hard way!
- Download the necessary tools, Etche is a free and popular tool for creating bootable USB drives. You can download it from the official website.
- You'll need the actual macOS installer file, which you can obtain from the App Store or by creating a backup of your existing Mac.
- Launch Etche and follow these steps:
- Select the macOS installer file you downloaded.
- Choose the USB drive as the target device.
- Click "Write" to start the process.
If you encounter any errors during the process, try restarting Etche and retrying. Make sure you're using a compatible USB drive (USB 3.0 or higher). If you're using a Windows 10 or later system, you might need to enable Developer Mode in Windows Settings to allow the creation of bootable media. Once you've created the macOS bootable USB drive, you can use it to install or upgrade your Mac operating system. Just insert the USB drive into your Mac, restart it, and hold down the "Option" key while booting up.
